Method for the combustion of a fluid fuel, and burner, especially of a gas turbine, for carrying out said method

A combustion chamber for a gas turbine engine, comprising:

• a combustion chamber housing having an inward side and an outward side;
• a combustion chamber wall formed on the inward side of the combustion chamber;
• a plurality of heat resistant elements affixed to an interior of the combustion chamber wall that define a combustion air flow channel;
• a primary burner having a first primary flow channel comprising a first primary outlet and a second annular flow channel concentric with and surrounding the first primary flow channel and comprising a second annular flow channel outlet, wherein the first and second flow channels comprise a common longitudinal axis and are separated by a common annular wall;
• a first catalytic burner comprising:
• at least a first catalytic burner flow channel having a first catalytic burner flow channel outlet;
• a first catalytically effective element disposed in the first catalytic burner flow channel;
• the first catalytic burner flow channel predeterminedly arranged to face into the primary flow channel in a approximately circumference direction of the primary flow channel;
• the first catalytic flow channel outlet arranged to direct a flow of a first fuel onto an inner surface of the common annular wall that defines an outer perimeter of the primary flow channel, such that the inner surface of the common annular outer wall is effective to impart circumferential motion to the first flow and create a vortex in the primary flow channel about the common longitudinal axis, wherein the first fuel is catalytically pre-reacted by exposure to the first catalytically effective element;
• and
• a second catalytic burner comprising:
• at least a second catalytic burner flow channel with a second catalytic burner flow channel outlet;
• a second catalytically effective element disposed in the second catalytic burner flow channel;
• the second catalytic burner flow channel predeterminedly arranged to face into the second annular flow channel in an approximately circumference direction of the annular flow channel and the a second catalytic burner flow channel and the second catalytic burner flow channel outlet arranged to direct a flow of a second fuel onto an inner surface of an outer wall that defines an outer perimeter of the second annular flow channel, such that the inner surface of the a second annular flow channel outer wall is effective to impart circumferential motion to the second flow and create a vortex in the second annular flow channel about the common longitudinal axis, wherein the second fuel is catalytically pre-reacted by exposure to the second catalytically effective element, and
• wherein subsequently a homogeneous non-catalytic secondary reaction is ignited downstream of the primary burner fuel outlet.
